Holiday Crash Data

The Department, as provided by law, collects motor vehicle crash reports from law enforcement agencies throughout the state of Illinois. The Illinois Vehicle Code precludes the Department from furnishing copies of crash reports, or related attachments, to anyone other than the original investigating law enforcement agency, or to federal, state, and local agencies engaged in highway safety research and studies. Crash reports and investigations conducted by the Department are confidential under the Illinois Vehicle Code (625 ILCS 5/11-408 and 11-412). Reports by law enforcement officers are confidential under Section 11-408(b), and individual motorist’s reports are confidential under Section 11-412. If you want a copy of a crash report, you must contact the law enforcement agency that investigated the crash. Illinois law does not allow the Department to provide copies of crash reports or divulge any personal information related to the crash, other than noted earlier herein. The law also stipulates that investigating agencies may furnish copies at a fee not to exceed $5 each.
